Note: All specifications subject to change without notice. Specify voltage and ambient condition upon ordering. MCA: Minimum circuit amps per UL 1995. MOCP: Maximum overcurrent protective device per UL 1995. STANDARD FEATURES: • Controls: Electronic programmed temperature controller with constant (set point & process) temperature readout. • Refrigeration Components: Efficient scroll compressors, sight glass/moisture indicators, balanced port expansion valves,

filter drier, pump down valves, fan cycling head pressure controls. • Process Fluid Components: Bronze “Y” strainer with 20 mesh stainless steel screen. Pumps are stainless steel centrifugal.

Tanks are insulated with shoe box lid, fill port, and level sight glass. Portable systems will include a bypass flow valve. • Safety Controls: High and low refrigerant pressure, high and low fluid temperature, freeze, low water flow, overloads for

compressor and fan motors, safety fuses or overloads for pump. • Construction: Welded steel powder coated frame and full metal cabinet, copper piping connections. • Warranty: One year parts / five year compressor.

SUITABLE AMBIENT CONDITIONS/FEATURES: • IND: Indoor use only. Casters on frame. • 40: Suitable for outdoor use with an ambient of 40°F ambient. Casters, optional. • 0: Suitable for outdoor use to 0°F ambient. Includes low ambient fan speed controls with (LT) models. Casters, optional. • M20: Suitable for outdoor use to -20°F ambient. Includes with low ambient fan speed controls with hot gas bypass.

External Wind baffles. Casters, optional.
